Based on the data of the investigation through the 8th to 14th of February, 1986, the atmospheric energy budget in a polygon area of the West Pacific Ocean (140-160°E, 18°S-14°N) has been calculated. It is shown that the total energy budget transports from outside toward inside of the polygon area. Among the all boundaries, however, the energy transfer only in the north- eastern boundary could display in opposite phase. Meanwhile, the major energy transfer would be by mean transfer rather than by disturbance. This study has also point out that there was the obvious warming-atmosphere phenomenon over the area during the investigation periods
